COUNTER AND STACKER.

Specification of Letters Patent.

Patented Nov. 1, 1910.

To all whom it may concern:

Be it known that I, EDMUND L. FEEMAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Counters and Stackers, ofwhich the following is a specification.

This invention relates to counters and stackers to be used in connectionwith certain machinery which delivers its products at one of its endsand the device is more especially adapted for the counting and stackingof envelops after they have been made by the ordinary envelop machineand delivered from the same.

The invention further consists of certain novel and simple details morefully described in the following specification, set forth in the claimsand illustrated in the drawings, wherein:

Figure l is an end elevation of an envelop machine showing the improvedstacker applied thereto. Fig. 2 is a plan view partly in section. Fig. 3is a detail view of certain intermittent mechanism.

In the manufacture of envelops, cartons, boxes and many other similararticles, it has been necessary after the delivery of same from themachine manufacturing them to pick them out one by one and count themfor delivery or for packing, this method has been laborious and tediousat the same time requiring the constant attention of an, In order toovercome this diffi-f culty the present device is provided andconoperator.

sists of delivery belts 5 mounted on pulleys 6 and 7, the pulleys 6being journaled on a stud 8 carried by the frame work 9 of the envelopmachine while the pulleys 7 are mounted on a shaft 10 carried by abracket 11 and an extension 12. As shown in Fig. 3 the shaft 10 isactuated by means of a rod 13 oscillated by any moving part of the envelop machine and carrying at its lower end a pawl 14 which with eachmovement of the rod 13 engages a difierent tooth of the ratchet wheel 15to turn the same. This ratchet wheel 15 is shown as having twentyfiveteeth all of the same size except the tooth 16 which is shorter than therest and allows the pawl to move inward near enough to the axis toengage a lever 17 forming one of the arms of a bell crank lever plvotedon the axis of the wheel and whose other arm 18 is connected by means ofa rod 19 with an arm 20 journaled in the frame of the machine at itsopposite side. As the wheel 15 is rotated by the pawl it also rotatesthe sprocket wheel 21 on the shaft 10 through the medium of the sprocketwheel 22 and chain 23 and by this means the belts 5 are intermittentlymoved as the machine operates. completed are fed through the rollers 24and 25 and on to the belts 5 and by which they are carried forward asthe pulleys 7 rotate.

The stud 26 to which the arm 20 is attached, carries an upright arm 27and pivoted to the upper rear end of the machine is a swinglng rod 28connected with the arm 27 by means of a link 29 which is connected withthe arm and rod by means of the adustable blocks 30. The lower end ofthe rod 28 carries a gathering and stacking board 31 having teeth 32which project through the spaces between the belts and has at its rearside rollers 33 which partly support same and relieve the belts of anyextra friction which the board 31 would otherwise cause. Connected withthe board is also an arm 34: to which the fork or rod 28 is secured andthe arm is long enough to extend beyond the fork and not pass through itbut always retain the board in front of the rod. The arm 27 and rod 28are provided with notches for the adjusting screws of the blocks 30 sothat the throw of the lower end of the rod may be varied to cause thestacking board to travel a greater or less distance and while theforward movement of the arm holds the board to the belts the backwardmovement tilts the arm 34 down and causes the rollers to carry the boardback and thus reduces the friction on the belt.

In operation, the rod 13 is continually reciprocated as before describedby some moving part of the machine and the pawl intermittently rotatesthe wheel 15 and causes the belts with the envelops to move slowly.When, however, the pawl reaches the tooth 16, it is permitted to extendfarther in toward the axis of the wheel and engage the end of lever 17which it raises, as it does the teeth and in so doing it thrusts the rod19 backward and rocks the arm 20 so that the arm 27 and rod 28 are putin motion and the stacking board 31 travels The envelops when over thebelts in front of the rollers and stacking all the envelops on that partof the belts into a pile and then immediately returns to its normalposition as shown in Fig. 1, leaving a space between the pile and thepoint where the envelops are being delivered. A spring 35 is provided toreturn the stacker to its normal position and the pile which has beenmade on the belts may be removed by the operator. The movement of thebelts is so slow that by this means several piles of envelops or otherarticles may be stacked upon them as they move onward but it is obviousthat the belts may be of such length as to accommodate any number ofpiles of envelops so that attention need not be given them for sometime.

The stud 8 and the bracket 11 are connected and braced by the rods 36which are adjusted by the turn buckle 87 and while the ratchet wheel 15is shown as having twentyfiveteeth, it is obvious that a wheel of anynumber of teeth may be provided to stack the number of articles that maybe desired as they come from the machine.

It is obvious that the details of this invention may be otherwisearranged and modified without departing from the essential featuresabove described.

What I claim as new and desire to secure by Letters Patent is:

1. In a stacker and counter, the combination with traveling belts, meansfor operating the belts intermittently, a stacking board traveling overthe belts, an oscillating arm carrying the same, and means connectedwith the operating means to swing the stacker forward after a certainnumber of intermissions.

2. In a counter and stacker, the combination with the delivery rollersof a machine, of moving belts, pulleys carrying the same, means forgiving'the pulleys an intermittent movement, a stacking board on thebelts before the rollers, a swinging arm carrying the board, anoscillating lever actuating the arm, and means connecting the lever withthe intermittent movement means to oscil late it at certain periods.

3. In a stacker and counter, the combination with the feed rollers of amachine, of traveling belts opposite the feed rollers, pulleys carryingthe belts, means for giving the pulleys an intermittent movement, a bellcrank lever connected with the intermittent movement means, a stackingboard traveling on the belts opposite the rollers, and means interposedbetween the bell crank lever and the stacking board to operate thelatter.

4. In a stacker and counter, the combina tion with the feed rollers, oftraveling belts in front of same, pulleys carrying the belts, means forgiving the pulleys an intermittent motion, a bell crank lever connectedwith and operated by the said means, a stacking board traveling over thebelts opposite the rollers, an oscillating arm carrying the same, armsmounted on a stud, a link connecting one arm with the bell crank lever,and a link connecting the other arm with the oscillating arm of thestacking hoard.

5. In a stacker and counter, the combination with the delivery rollersof a producing machine, of a plurality of moving belts before thedelivery rollers, pulleys carrying the belts, means for intermittentlyrotating the pulleys, a stacking board with teeth to fit between thebelts, rollers carrying the stacking board, a rearwardly extending armon the board, an oscillating lever connected with the arm and hung fromthe machine, rocking arms with links to operate the lever, and means foractuating the arms at certain intervals.

In testimony whereof I afliX my signature in presence of two witnesses.

EDMUND L. FEEMAN.
